EXECUTIVE SUMMARY Background The Forrestfield-Airport Link (FAL) project aims to construct a spur rail line from the Bayswater Station/Midland line through to the eastern suburb of Forrestfield and includes a station servicing the Perth airport. As part of this project, the Public Transport Authority (PTA) wish to confirm any affinities the vegetation in particular bushland locations in the High Wycombe locality may have with Threatened Ecological Communities (TECs). The survey area includes two discrete areas, Area 3 and Area 4. Area 3 bushland is bounded by Dundas Road and Maida Vale Road to the west and south and Palmer Crescent and Mack Place on the north side. Poison Gully creek flows through Area 3. Area 4 lies between Ibis Place, Sultana Road, Raven Street and Milner Road (Figure 1). The FAL survey area is located in the ‘Southern River Complex’ vegetation, on the Southern River unit of the Bassendean Dunes System on the Swan Coastal Plain (SCP). A search of the Department of Parks and Wildlife’s (DPaW) TEC and Priority Ecological Communities (PECs) database found that four TECs have been previously recorded within about 2.5 kilometres of the FAL survey area: SCP3a(Critically Endangered), SCP3b(Vulnerable), SCP20a(Endangered) and SCP20c(Critically Endangered) (Figure 2). Methodology In accordance with DPaW’s Draft Vegetation Survey Methods and Analysis to Determine Floristic Community Type/s for a New Site on the Southern Swan Coastal Plain (Department of Environment and Conservation 2011), ten quadrats (five in Area 3 and five in Area 4) were established and surveyed over two site visits. The first visit was undertaken in mid-Spring between 4 and 12 October 2014 and the second visit occured between 2 and 5 December 2014 (early Summer). Field Recordings Two quadrats in the eastern part of Area 4, ARQ13 and ARQ15, could be considered to have high species richness (75 and 67 native species respectively by comparison to Gibson et al. (1994) quadrat data). Quadrats ARQ5 and ARQ6 (Area 3) and ARQ9, ARQ10 and ARQ14 (Area 4) could be considered to have moderately high species richness. Quadrats ARQ7 and ARQ8 (Area 3, Poison Gully banks and adjacent slopes) and to a lesser extent ARQ11 (also Area 3) had low numbers of native taxa. This mostly reflected greater disturbance in those areas, reflected in greater weed

ii

cover with a commensurate loss of native taxa. The number of weed species in the survey quadrats (Table 1) was high compared to average numbers recorded by Gibson et al. (1994) in quadrats in the Bassendean Dunes System. The condition of the vegetation along the Poison Gully creek banks and adjacent slopes (Area 3) was mostly ‘Degraded’ along the creek banks with some of the slope vegetation in ‘Good’ condition. This vegetation formed a sizeable part of Area 3 in the form of a central, ‘linear’, meandering ‘corridor’ between the south-eastern end of Area 3 to its north-western end. Vegetation on the upland flats on the northern side of Poison Gully was in ‘Very Good’ condition. Much of the perimeter of Area 3 was ‘Completely Degraded’. The vegetation condition in Area 4 was regrowth that was mostly in ‘Very Good’ condition. Floristic Community Type Analysis The floristic analysis was conducted by Mr Ted Griffin on the quadrat data and the Gibson et al. (1994) SCP data set. Quadrat data in Area 3 and Area 4, with the exception of the Poison Gully site ARQ7 and to a lesser extent ARQ8, was considered reasonably compatible with the Gibson et al (1994) SCP dataset, on the basis of species richness (numbers of species) and species name reconciliation. The ten survey quadrats, together with six quadrats from a survey commissioned by the PTA in the surrounding area, were combined with the 509 SCP dataset for analysis. PATN was used to analyse the ‘all-sites’ dataset using a dendrogram classification and nearest neighbours (NNB) analysis. After reviewing the results, the data was re-analysed using a single site insertion method (SSI) whereby each of the survey quadrats were analysed, one at a time, with the 509 SCP dataset. The vegetation in the FAL survey area was found to variously have affinities with FCT3b, ?FCT3c, ?FCT11, FCT20c, FCT21a, FCT21c and FCT28. Areas of these FCTs were mapped (Figures 5 and 6). Sites ARQ7 and ARQ8 sampled vegetation along the banks and slopes of Poison Gully and were tentatively assigned to FCT11 and FCT3c (?FCT11 and ?FCT3c) and mapped together as ?FCT11/?FCT3c. FCT3b, 3c and 20c are listed as Threatened Ecological Communities by DPaW:

• SCP3b (Vulnerable): ‘Eucalyptus calophylla – Eucalyptus marginata woodlands on sandy clay soils of the southern Swan Coastal Plain’ (Swan Coastal Plain).

• SCP3c (Critically Endangered): ‘Eucalyptus calophylla – Xanthorrhoea preissii woodlands and shrublands, Swan Coastal Plain’ (Swan Coastal Plain).

• SCP20c (Critically Endangered): ‘Shrublands and woodlands of the eastern side of the Swan Coastal Plain’ (Swan Coastal Plain).

iii

FCT3c and FCT20c are listed under the Commonwealth EPBC Act of Threatened Ecological Communities (Australian Govt, 2015):

• ‘Corymbia calophylla – Xanthorrhoea preissii woodlands and shrublands of the Swan Coastal Plain’, Endangered

• ‘Shrublands and Woodlands of the eastern Swan Coastal Plain’, Endangered. FCT3b is not listed under the Commonwealth EPBC Act of Threatened Ecological Communities. FCT21c is listed as a Priority Ecological Community by DPaW (DPaW website, May 2014): ‘Low lying Banksia attenuata woodlands or shrublands (‘community type 21c’), Priority 3’. Recommendations It is recommended that further analysis be undertaken to further clarify the determination of FCTs in the study area by re-analysing the data after the removal of weed species and the inclusion of SCP Supplementary data from the eastern Swan Coastal Plain.

1.0 INTRODUCTION 1.1 Background The Forrestfield-Airport Link (FAL) project aims to construct a spur rail line from the Bayswater Station/Midland line through to the eastern suburb of Forrestfield and includes a station servicing the Perth airport. Its alignment will generally follow Tonkin Highway and then deviate towards Perth Airport where it will run beneath the airport surfacing to the east. A flora and vegetation survey undertaken by GHD identified vegetation in the Forrestfield area as having affinities with a number of different Threatened Ecological Communities (TECs). Department of Parks and Wildlife (DPaW) were consulted to confirm these findings and concluded that the TECs considered most likely to occur in the Forrestfield area were: • SCP20a (Banksia attenuata woodland over species rich dense shrublands). • SCP20b (Banksia attenuata and/or Eucalyptus marginata woodlands of the

eastern side of the Swan Coastal Plain). • SCP20c (Shrublands and woodlands of the eastern side of the Swan Coastal

Plain). The Public Transport Authority (PTA) wish to determine which Floristic Community Types (FCTs) have greatest affinity to the vegetation in particular bushland locations in the High Wycombe locality and the conservation status of those FCTs. The results of the assessment will be used in the environmental approvals and Environmental Impact Assessment for the project. 1.2 Scope of the study The PTA directed that the survey should include a:

• Targeted TEC desktop assessment of existing literature and DPaW data • A two phase field survey of the survey areas to collect sufficient quadrat data

for analysis, with the main survey in Spring. • Undertake analysis of the data collected to determine which Floristic

Community Types (FCTs) have greatest affinity to the vegetation. The targeted TEC survey was to be undertaken in accordance with the following documents and guidelines:

• Guidance Statement No. 51 Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia (EPA, 2004)

• Terrestrial Biological Surveys as an Element of Biodiversity Protection, Position Statement No. 3 (EPA 2002)

2

• “Vegetation survey methods and analysis to determine floristic community type/s for a new site on the southern Swan Coastal Plain” (DEC, 2011 (unpublished draft)).

To achieve the goals of the PTA, including the guidelines in the referenced documents, it was determined that this survey should include the following:

• Desktop review on information on vegetation TECs and Priority Ecological Communities (PECs) in the survey locality;

• A two phase field survey of the study area vegetation, to record quadrat data suitable for analysis to determine the Floristic Community Types (FCTs) (and hence the existence of any TECs and PECs).

• Undertake a PATN analysis of the survey data to determine the vegetation FCTs.

• Map the FCTs in the study areas; • Map the vegetation condition of the study areas; • Report the results of the survey.

1.3 The survey area The FAL survey area covered in this report included two discrete areas of bushland, Area 3 and Area 4 (Figure 1). Area 3 bushland is bounded by Dundas Road and Maida Vale Road to the west and south and Palmer Crescent and Mack Place on the north side. Poison Gully creek flows through Area 3. Area 4 lies between Ibis Place, Sultana Road, Raven Street and Milner Road and includes Lot 12 Ibis Place, which has been under a Vegetation Conservation Notice (Department of Conservation and Environment, 2011) after it was cleared between December 2005 and December 2006. The areas of Area 3 and Area 4 are 3.0 and 3.5 hectares respectively.

2.0 SITE DESCRIPTION AND BACKGROUND INFORMATION 2.1 Physical Environment 2.1.1 Climate The Swan Coastal Plain (SCP), which includes the study areas, has a Mediterranean type climate with hot, dry summers and mild, wet winters. 2.1.2 Geomorphology of the survey area The SCP consists of a series of geomorphological elements which are sub-parallel to the present coastline (McArthur and Bettenay, 1960; Churchward and McArthur, 1980). Each of these geomorphic elements has distinctive geology, vegetation, topography and soils. The FAL survey area lies in one of these elements, the Bassendean Dune System (McArthur and Bettenay, 1960). The Bassendean Dune System is the most eastern of three main aeolian deposits on the Swan Coastal Plain that can be arranged in age sequence and is comprised of low dunes and occasional swamps (Churchward and McArthur, 1980). The Bassendean Dunes are represented by three units which differ mainly in the nature of the associated swamps. The FAL survey area lies in one of these units, the Southern River unit, which occurs where ‘sand appears to have been blown over the alluvial soils and so swamps often have a clay base’ (Churchward and McArthur, 1980). The Southern River unit was described as ‘sandplain with low dunes and many intervening swamps’. 2.2 Vegetation background 2.2.1 Regional vegetation The Interim Biogeographic Regionalisation for Australia (IBRA) biogeographic representation of Australia has been developed, that categorizes the Australian continent into regions of like geology, landform, vegetation, fauna and climate (Thackway and Cresswell, 1995). The Western Australian IBRA region boundaries were largely based on Beard’s Botanical District boundaries (Paczkowska and Chapman, 2000). The FAL survey area lies in the IBRA ‘Swan Coastal Plain’ biogeographic region and the ‘Perth’ biogeographic subregion (IBRA 6.1 in Environment Australia, 2010). Heddle et al. (1980) mapped the vegetation of part of the Drummond Botanical Sub-district at a very broad scale, describing a series of vegetation complexes. These are related groups of vegetation associations found on particular landform-soil units (geomorphic elements, see above). They mapped a total of 38 vegetation complexes on the SCP. The FAL survey area is located in the ‘Southern River Complex’. The Southern River Complex was described as consisting of an ‘open woodland of

6

Marri- Jarrah- Banksia on the elevated areas and a fringing woodland of Eucalyptus rudis-Melaleuca rhaphiophylla along the streams’ (Heddle et al., 1980). More recently, an alternative analysis of the plant assemblages on the SCP south of Gingin Brook was carried out using a floristic approach (Gibson et al., 1994) and was extended in 2000. The Gibson et al. (1994) survey included 509 sites and will be referred to hereafter as the SCP survey and SCP dataset. Analysis of the dataset identified 30 Floristic Community Types (with a further 13 subdivisions) in four floristic 'Super Groups' for the southern SCP. These units are defined at a similar level of synthesis to that of Heddle et al. (1980) (Trudgen, 1999). The four 'super groups' of sites correlate closely with the major geomorphological elements on the SCP (and also to rainfall), with the exception of one group which contained the seasonal wetlands, which includes sites across all geomorphological groups (Gibson et al., 1994). 2.2.2 Rare vegetation: Threatened Ecological Communities (TECs) and Priority Ecological Communities (PECs)

2.2.2.1 Western Australian Government TECs/PECs database The Department of Conservation and Land Management (now DPaW) developed a procedure for identifying TECs (Department of Environmental Protection 2000b; English and Blythe 1997). Ecological communities are defined as ‘naturally occurring biological assemblages that occur in a particular type of habitat’. TECs are assigned to one of four categories: 'Presumed Totally Destroyed'; 'Critically Endangered'; 'Endangered' or 'Vulnerable' (Department of Environmental Protection, 2000b). On the Swan Coastal Plain, twenty four TECs have been determined from floristic and other studies. Of these, twenty four have been confirmed as 'threatened' (Department of Environmental Protection, 2000b). Eighteen of these TECs are Floristic Community Types (FCTs) or Floristic Community Type subgroups, as identified by Gibson et al. (1994). DPaW also maintains a list of PECs, which include ‘possible threatened ecological communities that do not meet survey criteria or are not adequately defined’ (DPaW, unpublished). These are added to DPaW’s PEC list under Priorities 1, 2 and 3. Priority 4 status is given to “Ecological Communities that are adequately known, and are rare but not threatened or meet criteria for Near Threatened, or that have been recently removed from the threatened list. Conservation Dependent ecological communities are placed in Priority 5 (DEC, unpublished). The list of PECs (DEC, unpublished) includes some that are FCTs as identified by Gibson et al. (1994).

7

A search of DPaW’s TEC and PEC database found that four TECs had been recorded within about 2.5 kilometres of the FAL survey area (Figure 2). These TECs were:

• SCP3a (Critically Endangered): ‘Eucalyptus calophylla – Kingia australis woodlands on heavy soils, Swan Coastal Plain’ (Swan Coastal Plain).


• SCP20a (Endangered): ‘Banksia attenuata woodland over species rich dense shrublands’ (Swan Coastal Plain).


FAL survey Areas 3 and 4 lie within the buffers of SCP3a, SCP3b and SCP20c sites. 2.2.2.2 Commonwealth TEC database The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) provides a legal framework to protect and manage nationally and internationally important flora, fauna, ecological communities and heritage places—defined in the EPBC Act as matters of national environmental significance. The nine matters of national environmental significance to which the EPBC Act applies includes nationally threatened species and TECs. The EPBC Act’s Matters of National Environmental Significance includes a list of TECs (although they are not always consistent with DPaW’s list), but it does not include any listing for PECs. A search of the EPBC Act’s matters of national environmental significance list for the FAL survey area with a five kilometre buffer, found three TECs listed (Appendix 1). These were:

• ‘Eucalyptus calophylla – Kingia australis woodlands on heavy soils, Swan Coastal Plain’ (Swan Coastal Plain) (Endangered).

• ‘Claypans of the Swan Coastal Plain’ (Critically Endangered). • ‘Shrublands and Woodlands of the eastern Swan Coastal Plain’ (Endangered).

2.2.2.3 Other TEC/PEC records There have been a number of recent floristic surveys in regrowth vegetation at Lot 12, Ibis Place (part of Area 4) (Department of Conservation and Environment, 2010-2012; Morgan, 2013). Lot 12 was cleared between December 2005 and December 2006 and is under a Vegetation Conservation. Ecoscape (Australia) PL undertook floristic surveys in March 2007 and September 2007 and identified that the vegetation had an affinity with FCTs 20c, 21a and 21c. The DEC undertook a floristic survey in

8

December 2007 and identified affinity with FCTs 20c and/or 20a. Ecoscape (Australia) PL undertook another floristic survey in August and November 2009 and identified FCT 3a and affinity with FCTs 3b, 20c, 20a and 23a. In a study for Strategen in 2012, Morgan (2013) determined the vegetation at 12 Ibis Plce and a neighbouring Lot, to have affinities with FCTs 21c and 20a in the western part and with FCTs 3a, 3b, 20c in the eastern part. FCTs 3a, 3b, 20a and 20c are TECs and FCT 21c is a PEC (Priority 3). The bushland vegetation in Area 3 has been inferred as TEC SCP3a ‘Eucalyptus calophylla – Kingia australis woodlands on heavy soils, Swan Coastal Plain’ (Critically Endangered) and was considered to be the one of three most northerly occurrences of this TEC at the time of the Bush Forever publications (Department of Environmental Protection, 2000b). 2.2.3 Bush Forever Sites All of the Area 3 bushland lies within Bush Forever Site 45: Poison Gully Bushland, High Wycombe (Department of Environmental Protection, 2000a). Bush Forever Site 123 (Sultana Rd West Bushland, High Wycombe) lies about one kilometre south-east of the FAL survey area and its vegetation was determined to be TEC SCP20a (Department of Environmental Protection, 2000b).

3.0 METHODS AND LIMITATIONS 3.1 Timing of the survey Quadrats in the FAL survey area (Areas 3 and 4) were first recorded in mid-Spring between 4 and 12 October 2014 and were rescored (second visit) between 2 and 5 December 2014 (early Summer). 3.2 Vegetation survey 3.2.1 Collection of the quadrat data Locations were selected for survey quadrats that were representative of observed variations in the vegetation and habitat or which provided coverage of an area to determine if there was floristic variation over that area. Areas of vegetation were selected that had the least disturbance to vegetation structure and where possible, that had good numbers of native species with low weed cover (‘Very Good’ or better vegetation condition (Department of Environmental Protection, 2000b). This limited the options for locating the quadrats, especially in Area 3. Quadrat ARQ7 sampled the Poison Gully creek flood bank vegetation and had a vegetation condition of ‘Good to Degraded’. The vegetation on the slopes adjacent to Poison Gully creek were sampled by ARQ8 and ARQ11, both considered to be in ‘Good’ condition. Area 4 quadrats were in vegetation considered to be in ‘Very Good’ condition, although it was regrowth vegetation after clearing. The survey quadrats were 10 metres by 10 metres in size. These quadrat dimensions were used because:

• The 10 metre by 10 metre quadrat size was used by the Gibson et al. (1994) SCP study. The quadrat data was analysed against the Gibson data set and therefore needed to be compatible with it.

• A 100 square metre sample area on the Swan Coastal Plain is considered to capture most species in any given plant community.

Quadrats were measured using a 50 metre field tape and were marked by fence pegs driven into the ground at each corner. Fence droppers fitted with yellow plastic safety caps were used to permanently mark the quadrats in Area 4. Black recycled plastic pegs were used to mark the quadrats in Area 3, because of perceived safety issues with the use of fence droppers in an area with high recreational use. Each quadrat was photographed. A description of the quadrat location, the habitat, surface soil texture and colour were all recorded and the time since the site was last burnt was estimated. The vegetation structure was described using a modification of Specht's vegetation description table by Aplin (1979; Appendix 2). The condition of vegetation in the quadrat was described using the Keighery classification outlined in Bush Forever (Department of Environmental Protection, 2000b; see Appendix 3). All plant species

12

occurring in a quadrat were recorded, along with their height, percentage cover and specimen number if collected. The DPaW FloraBase website was consulted as required to confirm the conservation status of a plant species recorded in the survey area (Conservation code definitions are listed in Appendix 4). Ten quadrats were recorded in the Areas 3 and 4. Five quadrats, ARQ5, ARQ6, ARQ7, ARQ8 and ARQ11 were recorded in Area 3. Five quadrats, ARQ9, ARQ10, ARQ13, ARQ14 and ARQ15, were recorded in Area 4 (see Figures 3 to 6). 3.2.2 Limitations of the quadrat survey The major limitation of the survey was that any such survey is a sampling procedure of a variable environment with plant populations of variable growth habit, life span and flowering season. Some species, including annuals, are only available for collection for part of the year. This means that to locate all species that grow in an area is a substantial task, the success of which is related to the timing of the survey, the time available and the size and diversity of habitat in the survey. To minimise this limitation and to make the dataset compatible with the SCP dataset, the survey included two site visits, one of which was conducted during the optimal Spring season. Factors that affected the numbers of species present in the vegetation units, including weed cover, past physical disturbance and rabbit grazing, were a limitation to the survey. While quadrat site selection in areas of ‘Very Good’ vegetation condition or better minimised this limitation, the limitation was more significant for sites such as ARQ7 (‘Good’ to ‘Degraded’), ARQ8 (‘Good’) and ARQ11 (‘Good’). 3.3 Mapping vegetation condition Vegetation condition was mapped across the survey area by extrapolating the vegetation condition assigned to the quadrat sites to the surrounding areas, if applicable, and was mapped while traversing the survey areas. The vegetation condition boundaries were drawn on a computer generated aerial photograph, using GPS coordinate readings as necessary to locate actual boundary positions. 3.4 PATN analysis of vegetation units and Floristic Community Types (FCTs) 3.4.1 Introduction PATN analysis (numerical classification techniques) compared the similarity of species presence data collected at the six survey quadrats with the 509 site SCP dataset (Gibson et al., 1994).

13

3.4.2 Data compatibility The survey data was, for most quadrats, reasonably compatible with the SCP dataset. Both datasets were based on data collected from quadrats of the same size (10 metres by 10 metres) from two visits per site including one in optimal season (Spring). Most of the survey quadrats were also recorded in vegetation that was in Very Good or better condition, which meant the vegetation structure was mostly intact. The exceptions to this were three quadrats in Area 3 ARQ7, ARQ8 and ARQ11 on the Poison Gully creek banks and adjacent slopes, which were discussed in Section 3.2.2. Overall, the differences in quadrat sampling with the SCP dataset were kept to a minimum, with the exceptions noted above, particularly quadrat ARQ7. 3.4.3 Data preparation Before conducting the analysis of the survey quadrat data, it was necessary to first reconcile the plant taxa names used in that survey with those used in the SCP dataset. This was done by determining, for each taxa recorded in the FAL survey area, the equivalent taxa name applied in the SCP study. This step was necessary because of changes in the nomenclature over the last twenty years and the potential for survey specific variations in the application of names. The reconciliation involved reducing some infra-specific names to the relevant species name, combining some taxa where confusion is known to have occurred in field observations and identifications and omitting some names (mostly where a taxon had only been identified to genus). The FAL survey area quadrat data was then added to the SCP dataset site-species table. In accordance with the methodology employed by Gibson et al. (1994) weed species were included in the analysis. 3.4.4 PATN analysis and determination of FCT Mr Ted Griffin undertook the PATN analysis of the quadrat data. Following the reconciliation of the data sets, a PATN analysis was undertaken on the combined datasets that included the ten quadrats in Areas 3 and 4 together with 6 quadrats from a survey commissioned by the PTA in the surrounding area (not reported in this document) and the 509 SCP sites. A dendrogram classification and a nearest neighbour analysis were conducted as two methods to determine site FCTs. After reviewing the initial results of the combined PATN analysis, it was decided to run a single site insertion (SSI) analysis, in which each survey quadrat was, one at a time, analysed with the 509 site SCP dataset. SSI is considered a more powerful and reliable means of deriving a dendrogram classification for each survey quadrat as it more accurately groups the tested site with the SCP dataset FCT groups because the one additional site causes less disruption to the SCP dataset FCT groups. When all test sites are included together in an analysis with the SCP dataset sites, it can cause

14

disruption and some reorganisation of the SCP dataset FCT groups (Griffin and Trudgen, 2004). The SSI classification analysis is closely analogous to the Gibson et al. (1994) analysis that determined the FCTs because it uses the same algorithm for the classification used by Gibson et al. (1994), with only the one additional site considered. The nearest neighbour analysis (NNB) isn’t a classification process, but is an indirect process for assigning a SCP FCT to a survey site by determining which SCP dataset sites are most floristically similar to it (measured by an index of dissimilarity). Each of the survey quadrats could, in turn, be assigned to the same FCT as that of the most similar SCP dataset site. 3.4.5 Limitations of the floristic analysis It has been found in other floristic analyses that the addition of new sites to the SCP dataset to produce a combined classification, may disrupt the original Gibson et al. classification of sites (Griffin and Trudgen, 2004). The more data that is added, the higher the level of disruption. If this occurs it can make it difficult to assign the new sites to a Gibson et al. (1994) FCT (Griffin and Trudgen, 2004). The application of a SSI classification largely overcame this limitation. Another limitation in conducting a PATN floristic analysis using the above methods may arise depending on the degree of success in reconciling the two data sets. A further limitation may arise from any significant differences in data collection methods between the two surveys. However, the data sets were considered reasonably compatible for this data analysis. Finally, the success of the PATN analysis to assign a SCP FCT to survey quadrats can be limited to the extent that the type of vegetation in the study areas was sampled in the SCP survey, allowing comparison with the outcomes of the Gibson et al. (1994) SCP analysis. 3.5 Mapping FCTs 3.5.1 Methods of FCT mapping Vegetation floristic community types (FCTs) were mapped by assigning the FCTs determined for each quadrat, to the vegetation extending from the quadrat until the species composition was observed to change to that represented by another quadrat. Observed variation in vegetation structure associated with floristics was also used. The vegetation unit boundaries were drawn on a computer generated aerial image while traversing the study area, using GPS coordinate readings as necessary to locate actual boundary positions. Ortho-corrected aerial photography at scale 1:1250 was supplied by RPS. 3.5.2 Limitations of FCT mapping A significant limitation to mapping the FCTs was the difficulty in identifying the changes in the species composition that were contributing most to changes in FCTs.

15

Structural vegetation changes were of some use in Area 3 where, together with floristics, it helped identify the creek bank and adjacent slope FCT. 3.6 Identification of Threatened Ecological Communities (TECs) and Priority Ecological Communities (PECS). Once the survey quadrats were each assigned to a FCT, current lists of TECs and PECs on the Swan Coastal Plain (DPaW website (b), 2015) were consulted to determine the status of the FCTs.

4.0 FLORA IN THE SURVEY QUADRATS 4.1 Significant flora recorded in the survey quadrats Conospermum undulatum (Threatened) was recorded in quadrat ARQ5 and near quadrat ARQ6 in Area 3 and Platysace ramosissima (Priority 3) was recorded in quadrat ARQ15 in Area 4. Another taxon recorded in the survey quadrats, Dasypogon obliquifolius, is considered Regionally Significant because stands in the Perth region are considered ‘populations disjunct from their known geographical range’ (Department of Environmental Protection, 2000b). While there have been some recordings of Dasypogon obliquifolius on the eastern SCP in the Perth region, its main area of distribution is north from about the Moore River to the region around Leeman. A list of flora taxa recorded from the quadrats in Area 3 and Area 4 and some additional species found within the immediate surrounds of the quadrats are included in Appendix 4.

17

5.0 RESULTS OF THE QUADRAT SURVEY AND VEGETATION CONDITION MAPPING 5.1 Quadrat descriptions Descriptions for quadrats recorded in Area 3 (ARQ5, ARQ6, ARQ7, ARQ8 and ARQ11) and Area 4 (ARQ9, ARQ10, ARQ13, ARQ14 and ARQ15) are presented in Appendix 6. Photos of the quadrats are included as Plates 1 to 10. 5.2 Quadrat species richness Numbers of species recorded in each quadrat are shown in Table 1. Quadrats ARQ13 and ARQ15 could be considered to have high species richness (by comparison to Gibson et al. (1994) quadrat data). Quadrats ARQ5, 6, 9, 10 and 14 could be considered to have moderately high species richness (by comparison to Gibson et al. (1994) quadrat data). Quadrats ARQ 7 and 8 and to a lesser extent ARQ11 had low numbers of native taxa. This mostly reflected greater disturbance in those areas, reflected in greater weed cover with a comensurate loss of native taxa. The number of weed species in the survey quadrats (Table 1) was high compared to average numbers recorded by Gibson et al. (1994) in quadrats in the Bassendean Dunes System. Table 1.

5.3 Vegetation condition The vegetation condition, and relevant extents, for Areas 1 and 2 are shown in Figures 3 and 4. The condition of the vegetation along the Poison Gully creek banks and adjacent slopes was mostly ‘Degraded’ along the creek banks with some of the slope vegetation in ‘Good’ condition (‘Good/Degraded’ in Figure 3). This forms a central, ‘linear’ part of Area 3 that meanders from its south-eastern end to its north-western end. Quadrats 5 and 6 were on the upland flats on the northern side of Poison Gully and were in vegetation in ‘Very Good’ condition. Much of the perimeter of Area 3 was ‘Completely Degraded’. The vegetation condition in Area 4 was regrowth that was mostly in ‘Very Good’ condition, with good numbers of native taxa with high cover and fairly low weed cover (Figure 4). Several areas in Area 4 had ‘Good’ or ‘Good to Degraded’ condition, where the weed control was markedly poorer than elsewhere and native taxa numbers were lower. One small area in the northern corner of Area 3 was a *Ehrharta calycina tussock grassland with almost no natives (Figure 4).

6.0 FLORISTIC COMMUNITY TYPES, THREATENED ECOLOGICAL COMMUNITIES AND PRIORITY ECOLOGICAL COMMUNITIES This section outlines the results of the floristic analysis conducted by Mr Ted Griffin on the survey quadrat data and the SCP data set. It is based on a report prepared by Ted Griffin, which is included in Appendix 7. 6.1 Floristic analysis 6.1.1 Data compatability Quadrat data in Area 3 and Area 4 was variable in quality. Poor site vegetation condition, reflected in poor native species numbers, meant site ARQ7 in particular was poorly compatible with the SCP dataset. The compatibility of site ARQ8 with the SCP dataset was also questionable for the same reasons. Other sites in Areas 3 and 4 could be considered reasonably compatible with the SCP dataset, on the basis of species richness (numbers of species) and names (reconciled) and was considered adequate to obtain reasonable FCT determinations. 6.1.2 PATN analysis and FCTs The results of the PATN classification dendrogram and NNB analysis of all the survey quadrats (ten in Area 3 and Area 4 and six from a survey commissioned by the PTA in the surrounding area, not covered in this report) together with the 509 site SCP dataset, are presented in Table 2 and in more detail in Appendix 7. The results of the SSI PATN classification are also shown in Table 2 (dendrogram shown in Appendix 7), along with Griffin’s summary analysis results and the interpretation of the analysis results by the author of this report. FCTs determined for Areas 3 and 4 were FCT3b, FCT4, ?FCT3c, ?FCT11, FCT20a, FCT20c, FCT21a, FCT21c and FCT28. The average number of weed species recorded in the Gibson et al. survey sites for FCTs 3a, 3b, 3c, 20a, 20c, 21a and 21c, are shown in Table 3. In reviewing the results of the PATN analysis, it was noted that weed species numbers were considerably higher in the survey quadrats (Table 1 above) than the average numbers per site for the SCP FCTs (Table 3). This is, for example, likely to bias the analysis results away from FCT20a (which has an average of 1 weed species per site). The particular weed species found in the survey quadrats may have a further biasing effect. 6.1.3 Occurrence of taxa indicative of particular FCTs The occurrence of particular species in an area of vegetation may provide a basis for inferring a FCT or limiting the possible FCTs that could be assigned to that vegetation. For example, Dasypogon obliquifolius is restricted to a section of the

23

eastern SCP in the Perth region and its abundance in parts of Area 3 and in Area 4 would indicate that the FCTs in the study area would be restricted to eastern SCP FCTs. Furthermore, Dasypogon obliquifolius was only recorded in the SCP survey quadrats assigned to FCTs 20a and 20b (Table 4) and its presence in parts of Area 3 and Area 4 could suggest that the vegetation must be FCT20a or 20b. Similarly Conospermum undulatum, which occurred in parts of Areas 3, occurred in 29% of SCP FCT20a sites (2 sites) and was only recorded in FCT20a sites (Table 4). However, a degree of uncertainty exists when forcing sites, on the basis of the presence of particular species, to FCTs that differ from those determined by analysis. The uncertainty arises if the study area vegetation wasn’t sampled in the SCP survey and could be part of vegetation variation not sampled by the SCP dataset. Inconsistencies arise between species present in the survey quadrats and their association with particular FCTs. For example, at the same site you may have one taxon that was only recorded in SCP FCT20a sites, while another taxon in the same site may only have been recorded in sites belonging to a different FCT. For this reason, the author has largely accepted the FCTs determined by the analysis, but has added FCTs to the results where the presence of key species indicated the occurrence of those FCTs (see Table 2). It should be noted that DPaW use a more powerful tool to infer FCTs on the Swan Coastal Plain, in the form of a (draft) key that assesses combinations of species present at a site to determine FCT (Val English, DPaW; pers. comm.). The draft key, which is not available to the general public, was developed by Gibson. This analysis could not be used in this study, but was applied by Val English when independently assessing FCTs in the FAL study area in 2014 (Val English, pers. comm.).

6.1.4 Geographic occurrence of Floristic Community Types (FCT) Google Earth was used to find the nearest Gibson et al. sites to Areas 3 and 4 on the eastern Swan Coastal Plain. These sites, their assigned FCTs and their distance from the FAL study area are:

• Three FCT20a sites in the Forrestfield area, 2.0 to 3.5 km south. • FCT23a and FCT21c sites in Bickly Rd bushland, Kenwick 7 km south. • FCT20c and FCT3c sites in Talbot Rd Bushland, Stratton, 9.5km. • FCT23a sites in Canningvale, about 16.5km south-west. • FCT21c sites in Forrestdale, about 22km south. • FCT21a sites near Forrestdale Lake, 23.5 km south. • FCT21a sites west of Muchea, 44km north-west.

While we can note that FCT20a vegetation occurs within 3 kilometres of the FAL study area, the SCP survey vegetation sampling in the locality of the study area can be considered sparse, a result of the very large SCP survey area that was sampled by the sites as well as the limited availability of remnant vegetation in the region. This means that inferences about the FCTs based on the proximity to SCP FCT sites, are fairly tenuous and of limited use. Therefore, no changes were made to the FCT determinations after consideration of proximity to SCP survey sites. 6.1.5 FCTs determined for the FAL survey area The vegetation in the FAL survey area was found to variously have affinities with FCT3b, ?FCT3c, ?FCT11, FCT20c, FCT21a, FCT21c and FCT28 (‘Authors Final FCT Determination’, Table 2) (Figures 5 and 6). The descriptions of these FCTs are (Gibson et al., 1994): FCT3b: ‘Eucalyptus calophylla – Eucalyptus marginata woodlands on sandy clay soils’ (Pinjarra Plain). FCT3c: ‘Eucalyptus calophylla – Xanthorrhoea preissii woodlands and shrublands (Pinjarra Plain). FCT 11: ‘Wet forests and woodlands’ (Bassendean/Pinjarra). FCT20c: ‘Eastern shrublands and woodlands’ (Ridge Hill/Pinjarra) FCT21a: ‘Central Banksia attenuata- E. marginata woodlands’ (Bassendean/Spearwood) FCT21c: ‘Low lying Banksia attenuata woodlands or shrublands (Bassendean). FCT28: ‘Spearwood B. attenuata or B. attenuata-Eucalyptus woodlands’ (Spearwood).

27

These determinations reflected not only the PATN analysis results and the factors discussed in the preceding section, but also the proximity to sites near by which were considered to be sampling vegetation with the same floristics and in better condition. Sites ARQ5 and ARQ6 in Area 3 were close to each other, with ARQ5 considered to be in vegetation in better condition and therefore given more weight. ARQ9, ARQ10 and ARQ14 were in close proximity and were considered to be sampling the same vegetation floristics. Similarly, ARQ13 and ARQ15 were also considered together. Vegetation in part of Area 3 was found to group with or have affinity for FCT28, which is considered to be a Spearwood unit. This is an unusual finding for the an area on the eastern Swan Coastal Plain, as most of the SCP dataset FCT28 sites occurred well to the west on the Karrakatta and Cottesloe landform units (yellow sands), with an outlier group of sites at the base of the Dandaragan Scarp. However, the Area 3 survey sites ARQ5 and ARQ6 occurred in an area with yellow sands present, and this may explain the floristic affinity with FCT28. The SSI classification of ARQ7 to ?FCT11 was accepted as an approximate determination due to ARQ7 joining with ?FCT11 at a high dissimilarity coefficient (>0.7). The condition of the vegetation along the Poison Gully creek banks meant the data would always be of questionable compatibility. That was exacerbated by the fact that the dominant shrub along the creek banks, Trymalium odoratissimum subsp. odoratissimum, was only recorded at one site (FCT6) in the SCP dataset, suggesting that this vegetation was poorly sampled in the SCP survey, probably due to it being a fairly unusual vegetation type on the heavily cleared eastern SCP. Another shrub commonly occurring along the creek banks, Thomasia macrocarpa, does not seem to be in the SCP dataset and does not appear in the flora list for the southern SCP flora recognised at the time of the survey (Gibson et al., 1994). The FCTs determined for Area 4 are in alignment with results from pevious surveys (Section 2.2.2.3). 6.1.6 Status of the FCTs in the FAL survey area: Threatened Ecological Communities and Priority Ecological Communities The conservation status of the FCTs that were determined for the vegetation in the survey area are summarised in Table 5.

7.0 CONCLUSION AND RECOMMENDATIONS 7.1 Conclusion 7.1.1 PATN analysis and FCTs and TECs in the study area The data from most of the quadrats in Areas 3 and 4 could be considered reasonably compatible with the SCP dataset (species names and species numbers were generally high) and therefore suitable for PATN analysis. Site ARQ7 (Area 3) was poorly compatible with the SCP dataset due to the poor condition of the vegetation reflected in low numbers of native species. The compatibility of site ARQ8 with the SCP dataset was also questionable for the same reasons. The quadrats in Areas 3 and 4 were found to variously have affinities with FCT3b, ?FCT3c, ?FCT11, FCT20c, FCT21a, FCT21c and FCT28, and these affinities, in some cases to more than one FCT, were mapped. The area of vegetation on the banks and slopes of Poison Gully in Area 3 were mapped for FCTs together. While the slopes vegetation was found to be ?FCT3c, the bank vegetation was assigned to ?FCT11 The fact that the NNB analysis showed Areas 3 and 4 being similar to SCP dataset sites belonging to a range of FCTs is likely to be due, in part, to the vegetation in the study area not having been included in the SCP dataset and varying somewhat from the vegetation that was sampled in the SCP dataset. However, the much higher number of weed species in the survey quadrats than the average number of weed species in the SCP dataset sites is likely to have distorted the results and reduced the clarity of the results. The high number of weed species in the quadrats is particularly likely to bias the results away from FCTs with very low average numbers of weeds per site (eg FCT20a, average of 1 weed species per site) and towards sites with higher weed numbers (eg FCT3c, FCT20c, FCT21a, FCT21c and FCT23a (average of 4 to 6 weed species per site)), depending on the actual weed species. 7.1.2 Vegetation condition in the study area The condition of regrowth vegetation in Area 4 was mostly considered to be ‘Very Good’ with low weed cover and good native species numbers, albeit less in some parts (three sites in the western part of Area 4). The vegetation condition varied in Area 3 with a sizable area of the upland flats in ‘Very Good’ condition while the vegetation along Poison Gully banks and adjacent slopes was mostly Degraded (‘Good’ along parts of the slopes). ‘Degraded’ and ‘Completely Degraded’ areas occurred around the perimeters of Areas 3 and 4.

7.2 Recommendation A PATN analysis, including SSI, has been conducted on the survey data. It is recommended that the analysis is extended to refine and clarify the results and improve certainty in the findings. It is likely more definitive results could be obtained by re-running the analysis with weeds removed from the FAL data and the SCP dataset. The inclusion of DPaW SCP Supplementary sites from the eastern Swan Coastal Plain may also improve the analysis by increasing the variation and repetition within FCTs and by the addition of new Supplementary FCTs.

8.0 ACKNOWLEDGEMENTS Mike Hislop (Western Australian Herbarium) offered advice on the identification of some taxa. Ted Griffin conducted the PATN analysis and provided a report on the analysis, included in the Appendices. RPS did the GIS mapping.

- migratory species that are very widespread, vagrant, or only occur in small numbers

- some species and ecological communities that have only recently been listed

Not all species listed under the EPBC Act have been mapped (see below) and therefore a report is a generalguide only. Where available data supports mapping, the type of presence that can be determined from thedata is indicated in general terms. People using this information in making a referral may need to considerthe qualifications below and may need to seek and consider other information sources.

For threatened ecological communities where the distribution is well known, maps are derived fromrecovery plans, State vegetation maps, remote sensing imagery and other sources. Where threatenedecological community distributions are less well known, existing vegetation maps and point location dataare used to produce indicative distribution maps.

- seals which have only been mapped for breeding sites near the Australian continentSuch breeding sites may be important for the protection of the Commonwealth Marine environment.

For species where the distributions are well known, maps are digitised from sources such as recovery plansand detailed habitat studies. Where appropriate, core breeding, foraging and roosting areas are indicatedunder 'type of presence'. For species whose distributions are less well known, point locations are collatedfrom government wildlife authorities, museums, and non-government organisations; bioclimaticdistribution models are generated and these validated by experts. In some cases, the distribution maps arebased solely on expert knowledge.

APPENDIX THREE. Vegetation condition scale (Department of Environmental Protection, 2000). Pristine (1). Pristine or nearly so, no obvious signs of disturbance. Excellent (2). Vegetation structure intact, disturbance affecting individual species and weeds are non-aggressive species. Very Good (3). Vegetation structure altered, obvious signs of disturbance. For example, disturbance to vegetation structure caused by repeated fires, the presence of some more aggressive weeds, dieback, logging and grazing. Good (4). Vegetation structure significantly altered by very obvious signs of multiple disturbance. Retains basic vegetation structure or ability to regenerate to it. For example, disturbance to vegetation structure caused by very frequent fires, the presence of some very aggressive weeds at high density, partial clearing, dieback and grazing. Degraded (5). Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching good condition without intensive management. For example, disturbance to vegetation structure caused by very frequent fires, the presence of very aggressive weeds, partial clearing, dieback and grazing. Completely degraded (6). The structure of vegetation is no longer intact and the area is completely or almost completely without native species. These areas are often described as 'parkland cleared' with the flora comprising weed or crop species with isolated native trees or shrubs.

APPENDIX FOUR Conservation Codes for Western Australian Flora (Adapted from the DPaW website page (DPaW website, January, 2015)

T Threatened species Listed as Specially Protected under the Wildlife Conservation Act 1950, published under Schedule 1 of the Wildlife Conservation (Specially Protected Fauna) Notice for Threatened Fauna and Wildlife Conservation (Rare Flora) Notice for Threatened Flora (which may also be referred to as Declared Rare Flora).

• Flora that are extant and considered likely to become extinct, or rare and therefore in need of special protection, are declared to be rare flora

Species (taxa) which have been adequately searched for and are deemed to be, in the wild, either rare, at risk of extinction, or otherwise in need of special protection, and have been gazetted as such. The assessment of the conservation status of these species is based on their national extent. Threatened Fauna and Flora are ranked according to their level of threat using IUCN Red List categories and criteria: CR Critically Endangered - considered to be facing an extremely high risk of extinction in the wild. EN Endangered - considered to be facing a very high risk of extinction in the wild. VU Vulnerable - considered to be facing a high risk of extinction in the wild. X Presumed extinct species Listed as Specially Protected under the Wildlife Conservation Act 1950, published under Schedule 2 of the Wildlife Conservation (Specially Protected Fauna) Notice for Presumed Extinct Fauna and Wildlife Conservation (Rare Flora) Notice for Presumed Extinct Flora (which may also be referred to as Declared Rare Flora). Species which have been adequately searched for and there is no reasonable doubt that the last individual has died, and have been gazetted as such.

Priority species (P) P1: Priority One: Poorly-known species Species that are known from one or a few locations (generally five or less) which are potentially at risk. All occurrences are either: very small; or on lands not managed for conservation, e.g. agricultural or pastoral lands, urban areas, road and rail reserves, gravel reserves and active mineral leases; or otherwise under threat of habitat destruction or degradation. Species may be included if they are comparatively well known from one or more locations but do not meet adequacy of survey requirements and appear to be under immediate threat from known threatening processes. Such species are in urgent need of further survey. P2: Priority Two: Poorly-known species Species that are known from one or a few locations (generally five or less), some of which are on lands managed primarily for nature conservation, e.g. national parks, conservation parks, nature reserves and other lands with secure tenure being managed for conservation. Species may be included if they are comparatively well known from one or more locations but do not meet adequacy of survey requirements and appear to be under threat from known threatening processes. Such species are in urgent need of further survey. P3: Priority Three: Poorly-known species Species that are known from several locations, and the species does not appear to be under imminent threat, or from few but widespread locations with either large population size or significant remaining areas of apparently suitable habitat, much of it not under imminent threat. Species may be included if they are comparatively well known from several locations but do not meet adequacy of survey requirements and known threatening processes exist that could affect them. Such species are in need of further survey. P4: Priority Four: Rare, Near Threatened and other species in need of monitoring (a) Rare. Species that are considered to have been adequately surveyed, or for which sufficient knowledge is available, and that are considered not currently threatened or in need of special protection, but could be if present circumstances change. These species are usually represented on conservation lands. (b) Near Threatened. Species that are considered to have been adequately surveyed and that do not qualify for Conservation Dependent, but that are close to qualifying for Vulnerable. (c) Species that have been removed from the list of threatened species during the past five years for reasons other than taxonomy.

APPENDIX SEVEN. “PATN Analysis of the FAL survey quadrats”

Report by Ted Griffin

FCT Analysis Airport Rail Link Rail Quadrats for BR Morgan Ted Griffin December 2014

1

1.0 INTRODUCTION 1.1 Purpose of this report

The current report is intended to help clarify the assignment of Floristic Community type (FCT) designation to vegetation community (site) data. FCTs were defined by Gibson et al (1994) based on site data collected from vegetation on the Swan Coastal Plain. In particular, the potential that a Threatened Ecological Community (English and Blyth 1997) is represented by the data collected needs to be clarified. 1.2 Location of Airport Rail Link Sites The sites were from from four areas adjacent to Dundas Rd in the area around the Dundas

Rd-Maidavale Rd intersection, on the east side of the Kewdale rail freight yards. 1.3 Brief background to floristic analysis of vegetation on the Swan Coastal Plain

Floristic analysis (ie., analysis of variation in vegetation based on the species present, rather than description of structural variation and dominance) as a significant component of the understanding of the variation present in the native vegetation of the Swan Coastal Plain dates to Gibson et al (1994 – all references to the SCP survey in the current report refer to this publication), the first publication to document the floristics of the vegetation of a large part of the Swan Coastal Plain. While the SCP survey is based on a very significant amount of work, it must be viewed as a “first pass” survey, limited, in the context of the great variety of vegetation present in the very large area surveyed, by the relatively limited number (509) of sites (quadrats) it is based on. To a limited degree, this limitation has subsequently been addressed in an “update” to the work of the SCP survey (which describes additional units). However, there is no detailed publication of the results of this update available and the additional data used are not readily available in an appropriate form (ie., one that would enable ready comparison of new data to the overall data set). The units described by the SCP survey are a series of “floristic community types”, a “unit” whose rank is defined by the use within a study. The SCP survey surveyed a very large survey area and defined a relatively small number of floristic community types. Consequently, the floristic community types they have described are of a very high order (see Trudgen 1999, volume 1, for further discussion of this point). This is an extremely important point to fully grasp in interpreting the analysis presented by the SCP survey and in understanding the meaning of analysis of other data sets when they are compared to the floristic community types of the SCP survey. The important effects of the limited size data set used by the SCP survey and of the relatively small number of floristic community types defined by them, can be summarised by the following points:

1. the definition of all but two of the Threatened Ecological Communities for vegetation on the Swan Coastal Plain (English and Blyth 1997) has been based on the floristic community types of the SCP survey. It therefore follows, that with two exceptions, only vegetation units from one study that are different at a very high order of floristics are treated as rare by Government. No account is taken of other important differences, such as differences in structure and dominance;


2

2. for the definition of floristic community types to be robust, a sufficient sized

database is needed to give adequate precision in their definition. About half of the floristics community types (or sub types) of the SCP survey are based on less than 10 sites. It is likely that with a larger data set there would be significant alteration in the classification of those floristic community types from the SCP survey based on small numbers of sites.

3. as noted above, many (if not most) of the floristic community types defined by

the SCP survey are very broad. They contain very significant variation in floristics, structure and dominance. Some (or in more highly cleared parts of the Swan Coastal Plain much) of this variation may be rare by any reasonable definition, but it is currently “buried” within larger groups;

4. there is likely to be significant variation not sampled by the SCP survey. This includes some variation at a high level of floristic difference (see Trudgen 1999, volume 1, for an example of this) and undoubtedly quite significant (large!) amounts of variation at “medium” and “low” levels.

5. the document, and its use by Government, has focussed attention in the

environmental impact assessment process on the high level of units described, deflecting attention from the layers of variation beneath these units that also have significant conservation value.

From these points it is obvious that there is a need for a major “upgrade” to the floristic analysis of the vegetation of the Swan Coastal Plain to provide a more detailed floristic classification that considers not only more of the variation present, but explicitly recognises more of the variation present in formally described units. Obviously, such a reworking would have some effect on what vegetation is considered rare on the Swan Coastal Plain. It needs to be stressed that it would be very unlikely to find that any of the vegetation currently considered to be rare on the basis of the SCP survey’s classification was not rare. On the other hand, it is likely that such a review would very probably consider to be rare some vegetation which is not currently considered rare. 1.4 Data provided

It is very important in comparing different sets of floristic data that they are comparable in the application of names, in the intensity of the survey (ie, the effort of searching resulting in similar proportion of the flora at sites being recorded) and in the size of the site recorded. If the data from different data sets is not comparable in these ways, it reduces the clarity of the results of the analyses carried out. If the discrepancy in the comparability of the data sets is large, the results may become meaningless.

2.0 METHODS

2.1 Data Preparation

The data from the Airport Rail Link sites were provided into a standard MS Access based database designed for this type of data. One virtue of the database is that the species recorded at each site are stored against standard codes (numbers, those used by the Western Australian Herbarium) for each species. This facilitates ready comparison of data from different surveys stored in the same system. After the data were incorporated into the database (containing the data from other projects), a process of reconciliation of flora species names with those used in the SCP survey was undertaken. This step was necessary at least because of changes in nomenclature over the last ten years and the potential of survey specific variations in the application of names. The reconciliation involved: reducing some infra-specific names to the relevant species name, combining some taxa where confusion is known to have occurred in field

observations and identifications, and omitting some names (mostly, where a species had only been identified to genus). The reconciliation process was relatively straight forward as most of the names had already been standardised. Most reconciliation was to conform with the methods that the SCP survey used to manage confusing taxa plus some nomenclatural changes (see Appendix). 2.2 Comparability of datasets

It was not easy to make any firm conclusions about the compatibility of the data from general summaries. 2.3 Comparisons made

The data from the 16 sites plus the 509 sites from the SCP survey of the southern part of the Swan Coastal Plain (south of Gingin) were combined. This enabled various analyses to be performed. The main purpose was intended to assign the individual sites to the Floristic Community Types (FCTs) defined in the SCP survey. These data are provided in BM_Airport.mdb.) 2.4 Analyses carried out

The approach was the use of numerical classification techniques (PATN) based on the similarity of the floristic composition of the Airport Rail Link sites to sites in the SCP survey data set.

2.4.1 PATN

Several modules of the numerical classification package PATN (Belbin 1987) were used for the analyses. The parameter values were the same as used by the SCP survey used to ensure consistency of analysis with that study. The PATN modules used were ASO (calculation of similarity matrix), FUSE (classification based on the results of ASO), DEND (representation of classification) and NNB (determination of sites most similar to each site – nearest neighbours). The results of the analyses were imported into a database (BM_airport.mdb) so that site characteristics and previous classifications (eg., Floristic Community Types derived in earlier classifications) could be associated and various analyses based on these data could be performed. The assignment of floristic community types to the Airport Rail Link sites was made by summarising the results of two different methods: the classification, and the forty nearest neighbours. Experience demonstrates that the results of these are likely to vary, but that from nearest neighbours is likely to make more sense. To the classification dendrogram of the combined dataset the FCT assigned by the SCP survey was associated with the SCP survey sites. The apparent FCTs were assigned to the Airport Rail Link sites by interpreting the position of these sites in the dendrogram (particularly by the way they joined to the SCP sites. The 40 sites in the combined data set that were most similar to each of the Airport Rail Link sites were obtained from the nearest neighbour method (NNB). By associating those nearest neighbours from the SCP survey, the most likely FCTs for each of the Airport Rail Link sites were determined. An attempt was then made to reconcile these different assignments of a Floristic Community Type. 3.0 LIMITATIONS

It has been found in earlier projects that the addition of new sites to the SCP survey data set to produce a combined classification disrupts the original classification. The more data added, the higher the level of the disruption. This problem can make it difficult to assign Floristic Community Types to new sites using this method. Secondly, it is common for new data to group to their cohorts. In some cases this has proven to result from common deficiencies in the data, ie. whole groups of species missing. This absence tends to draw them together. The more sites in the added batch, the tighter they draw together. The analyses are conducted without personal knowledge of the sites and no photographs were provided.

4.0 RESULTS

4.1 Determination of floristic community type by classification

The classifications was strongly influenced by the new sites being much more similar to each other than to the SCP sites (Figure 1). Thus, determining the FCT from this classification was impossible. Figure 1. Relevant portions of Dendrogram

4.3 Combining the results

It is common for the classification to indicate a simple result and the nearest neighbour analysis to be less conclusive. This is more a product of the classification process often suggesting an over simplified view than of inconsistency of the analyses. It is important to appreciate that classification cannot be absolute; evidence for which is that when new sites are added to an analysis set some clusters can change. It remains to be demonstrated to what degree a new site should belong to an existing community even if it is quite similar to one or more members of a community. But commonly a new site is quite similar to more than one existing community. Table 2 Summary of results Site Dendrogram
